In step S104, compares display parameters and whether the first display parameters determine the display image of display with
One image test signal matches.
According to the disclosure example, corresponding first display parameters of at least two field pictures of acquisition can be compared
Compared with.Judge the changing value between two or more first display parameters according to comparison result.And display is determined based on changing value
The variation of display picture whether match with the first image test signal.For example, by two first of the two field pictures of output
Changing value between display parameters is matched with the display parameters of the first image test signal of input, be more than when matching rate or
When equal to predetermined threshold value, determine that the display image of output and the first image test signal of input match.When matching rate is less than
When above-mentioned predetermined threshold value, the display image of output and being mismatched with image test signal for input are determined.Matching rate for example can be with
Be output two field pictures two the first display parameters between changing value with input the first image test signal display
Similarity between parameter.Then matching rate is big greatly for similarity, and the small then matching rate of similarity is small.If identical, matching rate
It is 100%.The threshold value of matching rate can be set according to the setting of user.For example, it can be set to being 80% or 95%.Example
Such as, the display parameters of the first image test signal of input are for example including average brightness, Luminance Distribution value etc..
According to another example of the disclosure, the first image test signal also includes the broadcasting letter of two frames or multiple image
Number, the display parameters between two field pictures or the play signal of multiple image have default changing value.For example, can be pre-selected
Two field pictures or multiple image with default changing value are as the first image test signal.When the two field pictures for being extracted output
Or after the changing value between the first display parameters of multiple image, which is compared with default changing value above-mentioned,
Determine whether changing value matches with default changing value, and based on matching result determine display display picture variation whether with
First image test signal matches.For example, when the matching rate of changing value and default changing value is equal to or more than 90%, it is believed that defeated
Enter and matches with the signal of output.When the matching rate between changing value and default changing value is less than 90%, it is determined that input domain
The image of output mismatches.Certainly, above-mentioned matching rate can be set according to the demand of user.For example, required as user
When matching rate is high, then 97-100% is can be set as.When the matching rate that user requires is low, 80%-96% etc. can be set as.
In addition, according to another example of the disclosure, at least two field pictures of output can also be divided into multiple
Then region obtains the first display parameters of at least two field pictures of output again.For example, the region of division can be preset
Number, determines region area and the coordinate value in each region.For example, for dividing four regions, when will be in multiple image
After being divided into 4 regions per frame image, first display parameters in each region in 4 regions are obtained.Then, according to multiple areas
The position in domain is corresponding with a region of another frame by a region in a frame image.For example, working as first frame image and second
When frame image is divided into four upper left, lower-left, upper right, bottom right regions respectively, the top left region of first frame image and the second frame
The top left region of image corresponds to；The right regions of first frame image are corresponding with the right regions of the second frame image；First frame image
Lower left region it is corresponding with the lower left region of the second frame image；The bottom right area of the lower right area of first frame image and the second frame image
Domain corresponds to.Region correspond to after, based on multiple corresponding regions the first display parameters determine display display image whether with
First image test signal matches.For example, two the first display parameters of each corresponding region of two field pictures are respectively compared,
Two the first display parameters changing values of the corresponding region of the two field pictures are determined based on comparative result.For example, being respectively compared
The changing value of one frame image and first display parameters in corresponding four regions of the second frame image changes according to the first display parameters
Value, determines whether the display image of display matches with the first image test signal.
For example, when first frame image and the second frame image are divided into upper left, lower-left, upper right, the region of bottom right four respectively
When, the first display parameters of the top left region of the first display parameters of the top left region of first frame image and the second frame image carry out
Compare；First display parameters of the right regions of the first display parameters of the right regions of first frame image and the second frame image into
Row compares；First display parameters of the lower left region of the first display parameters of the lower left region of first frame image and the second frame image
It is compared；First display ginseng of the lower right area of the first display parameters of the lower right area of first frame image and the second frame image
Number is compared.The changing value between the first display parameters is determined more afterwards, then according to four the first display parameters changing values,
Determine whether the display image of display matches with the first image test signal.
For example, the display parameters by four the first display parameters changing values respectively with the first image test signal compare
Compared with display parameters for example can be image brightness distribution value, brightness of image average value etc..It is then based on comparison result and determines matching
Rate.When each corresponding region matching rate is all higher than or when equal to predetermined threshold value, it is determined that the display image of output and the of input
One image test signal matches.When the matching rate in each region is respectively less than above-mentioned predetermined threshold value, the display figure of output is determined
As being mismatched with the first image test signal of input.
Alternatively, further for example, the conduct the of two field pictures or multiple image with default changing value can also be pre-selected
One image test signal.Between being extracted the first display parameters of the corresponding region of two field pictures or multiple image of output
After changing value, which is compared with default changing value above-mentioned, determines the changing value of each corresponding region and preset
Whether changing value matches, and based on matching result determine display display picture variation whether with the first image test signal
Match.For example, when the changing value in each region is equal to or more than 90% with the matching rate of default changing value, it is believed that output
Display signal and input the first image test signal match.When between the changing value and default changing value in each region
When matching rate is respectively less than 90%, it is determined that the image of input and output mismatches.
According to another example of the disclosure, at least two field pictures are divided into multiple areas in output signal above-mentioned
In the embodiment in domain, can also further determine that corresponding region the first display parameters changing value and the first image test signal not
Matched corresponding region accounts for all ratios for dividing region.And according to the region rate judge display display image whether with
First image test signal matches.For example, when every frame image is divided into 10 regions, when have 2 corresponding regions
One display parameters changing value and the first image test signal mismatch, and the first display parameters changing value of 8 corresponding regions with
When first image test signal matches, then region rate is 20%.If region rate set by user be less than or equal to for
10%, then according to region rate, the region rate 10% for being more than setting due to 20% then may determine that the display image of display
It is mismatched with the first image test signal.
Further for example, when every frame image is divided into 10 regions, when the first display parameters variation for having 1 corresponding region
Value is mismatched with the first image test signal, and the first item video parameter changing value and the first image measurement of 9 corresponding regions
When Signal Matching, then region rate is 10%.If the user determine that region rate is less than or equal to being 10%, then it is current to mismatch
Region rate is equal to the region rate of the setting, then may determine that the display image and the first image test signal phase of display
